FEATURES AND BENEFITS:
- Excellent penetration into concrete surface
- Fully sprayable
- Excellent adhesion
- Ideal for line application
SURFACE PREPARATION:The application surface should be sound and clean, free from laitance, grease, oil, rust, scale, dirt, or any other soiling that might affect adhesion or performance. Shot blasting is recommended, but especially in the case of overcoating existing line markings, it is further recommended that test areas be coated to ensure good adhesion and/or compatibility with the substrate.
Examples of preparation methods that may be suitable are captive shot blasting, diamond grinding, scabbling or planing. It is critical that utmost attention is paid to cleanliness and good workmanship whatever preparation method is used, as the presence of any loose material, dust, soiling or previous coatings is likely to reduce adhesion of new coatings.
New concrete should be left to harden before coating for at least 3 weeks, as the curing process and residual moisture content can lead to product delamination if coated too early.
Stir thoroughly with mechanical mixer.
Thinning: This product is supplied ready to use and need not be thinned.
We recommend the use of airless spray equipment. Roller or brushes can be also be used if spray equipment is not available.
Temperature: Do not apply when the air or surface temperature is below 5°C or less than 3°C above dew point, or if this is likely to occur during the curing period. Do not apply when there is rain, mist, fog, or snow imminent; when humidity is high or the surface is wet with condensation or likely to be during the drying period.
CURING:Touch dry: 20 minutes @ 15°CWalk on time: 30 minutes @ 15°CTraffic time: 60 minutes @ 15°CFull cure: Minimum 1 hour @ 15°CRecoat: 1 - 2 hours @ 15°C Ensure fully cured before applying top coat.
